Mission Impossible is one of the most popular movie franchises of all time. Especially the later sequels, having put some of the greatest stunts ever put to film. But we would not have these spellbinding movies, if it weren't for Mission Impossible 3. MI:3 completely changed the tone and landscape of what these movies could be, and introduced a new style of action that would carry through the rest of the franchise. Mission Impossible 3 absolutely saved the franchise.
